It is in my experience - easily the most unpleasant experience of all the countries I’ve visited.

Even places with intense security concerns like Israel was better. More intense than the US but less powertripping assholes (no doubt this comment will get me into trouble too given their invasive social media bullshit)

Really depends on a country. Most countries's border crossing is not comparable to USA/UK/Israel.

TSA is not responsible for border crossings, they handle security.

The original dissatisfaction was with the whole travel/airplane/border process, no matter who is officially responsible. TSA is a government agency.
